PIBCV Flow Setting
½…1¼" Size Valves
The calculated flow can be adjusted easily without using spe-
cial tools. To change the presetting (factory setting is 100% for
separately purchased PIBCV valve bodies) follow the four steps
below:
1 Remove the black protective cover or the mounted actuator.
2 Raise the green pointer.
3 Turn (clock wise to decrease) to the new presetting.
4 Press the pointer back into the lock position. After the
pointer is clicked back into place the presetting is locked.
The presetting scale indicates values from 100% flow to 20%.
Clock wise turning would decrease the flow value while counter
clock wise would increase it.
Example: VP229E-15HN
With this ½" valve the nom flow
= 5 gal/min = 100% presetting.
To set a flow of 4 gal/min you have to set: 4/5 = 80%.
Schneider Electric recommends a presetting/flow from 20% to
100%.
To set a PIBCV valve to a Q
high
setting above 100%, turn the
green pointer counter clock wise from 100%. The Q
high
setting
is the scale setting plus 90%. For example, to set the VP229E-
15HN to a flow rate of 5.5 gal/min, set 5.5/5.0 = 110% setting.
Obtain the 110% setting by turning the green pointer counter
clock wise from 100% to 20% (20% and 90% = 110%). As
shown on page 230, Q
high
settings above 100% slightly in-
crease the valve’s required minimum differential pressure.
